I'm looking to pick up a hedge trimmer and I was wondering what you guys would suggest.I am adding the service for next year so I don't know how much I'll be using it, but I'd like to go w/ a shindaiwa. Would you suggest: double or single sided? Articulating or fixed blades? Mid-reach, "traditional" hand held, or a multi-tool system? (I have a chainsaw, but if I went with a multi-tool in the future I could get a pole saw maybe....) I realize its easier to decide on something if you know the exact use...but what is most flexible?
